Current controlled sigmoid neural circuit |
摘要 |
The current controlled sigmoid neural circuit is used for approximating sigmoid function and is simple constructed, current controlled and gain adjustable circuit with highly precision. The present invention comprises a voltage generator for converting a current input into a voltage, a pair of differential amplifier for generating sigmoid-like function and few pairs of current mirrors for providing reference currents. By using adjustable reference current and gain factor, the circuit has a large range and high noise immunity and can approximate sigmoid function with insignificant error.
